Three City Parks Making Their Comebacks

Palega Recreation Center Upgrade: $21.2 million
Social networking teens just got a slick new place to hang offline: this redone 80-year-old park in Portola with six acres of indoor-outdoor turf for basketball, volleyball, soccer, and fitness classes like boxing, Zumba, and martial arts.500 Felton St. (at Hamilton Ave.)

Cayuga PlaygroundUpgrade: $9.4 million
Artsy kids will dig the decorative entry gates and the whimsical sculptures in the flowerbeds at this pocket-size park in the Outer Mission. A curvy path for smooth skating surrounds a grassy field suited for sunbathing, and a playground with a new spiderweb climbing structure, swings, and a picnic table is nearby. Cayuga Ave. (at Naglee Ave.)

Cabrillo PlaygroundUpgrade: $4.5 million
Blink and you’ll miss the shiny jungle gym a block from Golden Gate Park in the hinterlands of the Outer Richmond, primed for young roamers to slide, teeter-totter, and bounce on structures sized for little feet. 38th Ave. (between Cabrillo and Fulton Sts.)
